Indeed, CIL exception applied for and commencement notice issued to the council today (with a written confirmation back from them that everything is in order for the exception). Looks like all is set for commencement for Thursday, woohoo.

Just use the name and address of someone else in the village?

Decision notice issued at 19:00 and granted, finally.

As an update, i got my building regs signed off this morning, grant of planning permission is due today. Who of thought i would have building regs signed off before planning granted. Ground workers on site in a couple of weeks, though need to get my self build exception in and agreed before then.

Just to build on this, the requirements for ADE for internal partitions (Rw 40 dB) is determined by a lab based measurement, you don't do testing on site for internal partitions. For separating walls and floor between dwellings (attached houses / flats) you have to do on site testing (unless using the Robust Details scheme), to demonstrate compliance of meeting the minimum requirements of ADE (new build Dn,Tw + Ctr >= 45 dB, Ln,Tw <=62 dB), testing requirement frequency is usually 10% of constructions on site.

No its not, those detailed in ADE are just examples of how you can meet the requirement of ADE for Rw 40 dB for internal partitions. You could have a partition floor made solely of cheese and as long as you had a lab test showing it met Rw 40 dB it would meet the requirements. Though meeting the fire regs for a cheese floor would be interesting, and a tasty fondue.

This construction is really a 'deemed to satisfy' construction, and what it satisfies is the requirement of ADE that the internal walls and floor meet min Rw 40 dB. You can meet Rw 40 dB with out the insulation and 18mm board, though with 15mm wall board ceiling. https://www.gyproc.ie/sites/default/files/C106029.pdf

Thanks, W18 and W19 are both 750mm x 750mm so 0.56m2 each, 1.12m2 in total. They are 2m apart so not acceptable (Diagram 11.5 of Approved document B). W16 is 600 x 600mm so 0.36m2 The floor above W16 is a standard timber floor but will have a minimum fire rating of 30 minutes (https://www.gyproc.ie/sites/default/files/C106029.pdf), so W16 is o.k. The issue is going to meet the requirements of Diagram 11.5 of Approved document B for the two windows as they don't have the separation required. I think the most straight forward solution is to drop W18 or W19 as these aren't really critical. Edit: spoke to the BCO all sorted.

I am coming to this issue, i have a façade on the boundary to the next door property, the actually building of the property is 1.5m away from the proposed facade, though there are three fixed obscure glazed windows in in the façade right on the boundary (W18, W19, W16), W17 is set further back The BCO has highlighted the this as a potential issue for fire, and should be fitted with fire resistant glass. The window proposed are aluminum 6.8mm Lam / 18mm Argon / 4mm Planitherm One. Any idea if this will the requirements?

what is the sewage from the main house? does it connect to a combined sewer? Our ground conditions don't allow for a soakaway, and luckily there is a combined sewer in the road in front of our house. We wrote to the local water authority who granted us to discharge surface water to the combined sewer.

This, it has to be phased. I have been through this process, and the local authority won't allow a phased development for two houses. Many other places do, and I know of one local authority self build spd that outlines the phased route for self build developments

Steel as well.

Thanks, i have sent them an enquiry, i will probably need less than 250.

@joe90 didn't you build a 200mm cavity masonry wall? what ties did you use? The SE spec says embedded a min 50mm into leaves, and its a 200mm cavity. So a 300mm tie would meet the spec and are available at a much more palatable price (£64 for 250) https://www.lbsbmonline.co.uk/wall-ties-dt300-double-triangle-300mm-box-of-250-cavity-tie

For the retaining walls on site the design is a 200mm filled cavity block work wall as below. I need to get the wall ties for this construction, which need to be 325mm to be embedded a min 50mm within each leaf. I am looking for a cost effective tie to buy which doesn't need to be special as they are going to be embedded in the concrete fill. They only need to hold the leaves together of the pressure when the concrete is poured. The ancon ST1 comes in 325mm but are expensive, and given the use in the filled wall they seem over kill. Any ideas?

ill give you a shout on PM

Did they do a noise survey at the property? if so make sure they account for the skew that Covid is having on traffic flows at the minute. When you say it goes over 1m, do you mean over a metre high? You shouldn't need planning as its replacing existing fencing https://www.planningportal.co.uk/info/200130/common_projects/20/fences_gates_and_garden_walls

likely to be fencing, on new developments typically it is only walls between private amenity spaces and public access roads / spaces for security. I wouldn't think that the flats car park wouldn't fall under public access, so no wall. Edit: Just looked at a large development i am working on and its fences between flats car park and house private amenity spaces.

when plastering first, what measurements have to be spot on? (i am planning on this route)

Caution if using this software as it only calcs axial modes, not tangential and oblique modes, which can cause issues as well though are not as strong as axial modes as get absorbed / diffused by room surfaces. Below is the room mode calc based on the modecalc example for all mode types (all = 0, axial = 1, tangential =2, oblique = 3), and there is a couple of tangential modes combining at around 75 Hz (75.3 and 75.5 Hz). In regard to modes you want to get a nice even modal density so that the frequency response of the room is as flat as possible and any spikes are smooths via absorption or diffusion.

yeh i think that i would prefer FB than painting on stuff.

I submitted my building control drawings and have had 3 comments back. One of these was "Gypsum fireline board should be used for fireproofing steels rather than wallboard". He indicated on the phone that 12.5mm fireline would be o.k. The details of the steel encasements are below The first one is in a garage and i think that the can be done easily, the second one i am not sure of as it has joists attached to it. in fact its going to have a board attached to the steel (box steel rather than I-beam shown) for the joist hanger to go onto, so am i going to have to box in the box steel and bolt through the fire board to secure the wood to the steel? Third one maybe easier to have a later of the ceiling as fireline? would that be enough?

more than likely yes.
